Remote controller using analog electronic switch

Abstract

The invention discloses a remote controller using an analog electronic switch. The remote controller comprises a signal conversion circuit, an analog switch integrated circuit, and a remote control chip; a control signal input terminal of the analog switch integrated circuit is connected with an external controller output terminal by the signal conversion circuit; and a controlled switch pin of the analog switch integrated circuit is connected with the input terminal of the remote controller chip. According to the invention, the control signal is used for controlling tuning on and turning off of the electronic switch; and the principle is simple and the performance is reliable. The signal transmission of the electronic switch integrated circuit is fast; and the response is carried out sensitively and rapidly.

Description

technical field [0001] The invention relates to the field of remote controllers, in particular to a remote controller using analog electronic switches. Background technique [0002] In the automatic production process of air conditioners, color TVs, set-top boxes and other products, it is often necessary to use equipment to automatically remote control the products produced, so as to automatically perform product inspection and testing. At present, different products need to use different remote controls, and it is difficult to use one remote control to control a different product; or, it is necessary to use the original remote control chip and program of the product for modification and use. [0003] Existing remote controllers use remote controller buttons instead of digital signals to control the use of remote controller chips. The traditional method is to use triodes and relays, but because the processing chip of the remote control is a matrix scanning button, it is not...
